我目前正在尝试对视频文件进行编码，ffmpeg -i input.mkv libx265 crf=28 -x265-params profile=main10 out.mkv但我得到的输出文件是 8 位的？
ffmpeg -i input.mkv libx265 crf=28 -x265-params profile=main10 out.mkv
如果输入还不是 10 位，则必须先转换它，通常使用-pix_fmt.
-pix_fmt
ffmpeg -i input.mkv -pix_fmt yuv420p10le -c:v libx265 -crf 28 -x265-params profile=main10 out.mkv
